On Friday, June 25, 2010, I pleasantly used this handy tool to fully uninstall a failed Adobe Reader 9.3.2 installation. To my surprise and great disappointment, the Windows Installer Cleanup utility (MSICUU2.exe) was discontinued over the weekend and is no longer available.

“Notice: This article previously contained a link to the Windows Installer Cleanup utility (MSICUU2.exe). If you were directed to this article to solve a problem installing a product other than Microsoft Office, please contact your software manufacturer for installation support on the product.”

Naturally, many third-party software manufacturers relied on the Windows Installer Cleanup utility to clean up their own mess. I sure wish I retained a copy of MSICUU2.exe, for it would come in handy today and likely many more times in the future.
